Saint Sophia Cathedral
The foundations were laid in 1037; the cathedral took two decades to complete. After the pillaging of Kiev in 1169, followed by Mongolian Tatars in 1240, the cathedral fell into disrepair. Repair started in 1633 and continued until 1767. After the Russian Revolution of 1917, and during the Soviet antireligious campaign of the 1920s, the government plan called for the cathedral's destruction. The cathedral was saved from destruction; however, in 1934, Soviet authorities confiscated the structure from the church, including the surrounding 17th-18th century architectural complex and designated it as an architectural and historical museum. On 21 August 2007, the Saint Sophia Cathedral was named one of the Seven Wonders of Ukraine.
